To beat the however reduced injection pressure of the mix of expanded thermoplastics necessary to fill the mould cavity, each station is equipped with a contrast pneumatic cylinder. This simple and functional closing system proposed guarantees correct seal and top-quality performance. As regards operations, this model is full electric for this choice has proved successful in terms of reliability and very low consumptions, lower than 4 kW/h.
